The size of the VoLTE market will be over $30 billion through 2019, said ABI Research.
While network vendors such as Ericsson and Nokia are committed to VoLTE and IMS space, Alcatel-Lucent, Huawei, and Cisco recognize the impact VoLTE and IMS will have on the market.
North American operators are leading the VoLTE driven IMS deployments, followed by Western European operators. IMS deployments are on a rise and will be widely deployed over the coming years, said ABI Research.
Alan Hadden, president of GSA, said: “71 operators are investing in VoLTE studies, trials or deployments, including 11 that have commercially launched HD voice service.”
The number of HD voice launches enabled by VoLTE is forecast to reach 19 by end-2014 and then double in 2015, said GSA on Monday.
ABI Research analyst Sabir Rafiq said: “Apple’s embrace of VoLTE with the iPhone 6 raises the bar and points the way for all device manufacturers to follow. IMS mobile core revenue corresponds directly with the popularity of VoLTE.”
VoLTE will become important in the future and ABI Research believes competitive positioning will lead operators to VoLTE / IMS.
ABI Research said that VoLTE subscriptions will significantly increase year-on-year as subscribers appreciate the voice quality and demand the additional services of the all-IP 4G LTE.
92 smartphones including products by Asus, Huawei, LG, Pantech, Samsung and Sony Mobile support VoLTE.
